A battery electric vehicle includes a passenger cabin, a refrigerant circuit adapted to cool the passenger cabin, a powertrain including a high voltage powertrain component, a coolant circuit adapted to cool the high voltage powertrain component and a control module. The refrigerant circuit includes a condenser and an evaporator. The coolant circuit includes a radiator downstream from the condenser. The control module is configured to recirculate cabin air to the passenger cabin in response to data indicating temperature of the high voltage powertrain component exceeds a predetermined threshold temperature in order to reduce the air outlet temperature at the condenser and the air inlet temperature at the radiator. A related method to cool a high voltage powertrain component of a battery electric vehicle is also disclosed.

A vehicle-mounted temperature controller, comprising: a first heat circuit having a heater core used for heating and a first heat exchanger and configured so that a first heat medium is circulated therethrough; a refrigeration circuit having the first heat exchanger condensing the refrigerant and an evaporator evaporating the refrigerant, and configured to realize a refrigeration cycle; and a heat medium flow path of an internal combustion engine configured to communicate with the first heat circuit so that the first heat medium circulates therethrough. The first heat circuit is configured so that an outlet of the heat medium flow path is communicated with a core downstream side part positioned downstream of the heater core and upstream of the first heat exchanger and a core upstream side part positioned downstream of the first heat exchanger and upstream of the heater core.

A method for optimizing climate control in an autonomous vehicle. The method includes receiving a ride request for an autonomous vehicle from a customer. A desired temperature for an interior of the autonomous vehicle may be determined based on the ride request. The current temperature of the vehicle interior may then be adjusted such that the current temperature substantially matches the desired temperature when the autonomous vehicle reaches the customer. The temperature of the vehicle interior may be allowed to deviate from the desired temperature, within a pre-determined temperature deviation range, when the autonomous vehicle is unoccupied. A corresponding system and computer program product are also disclosed and claimed herein.

Systems, apparatuses, and methods disclosed herein include a system including a heating, venting, and air conditioning (HVAC) system and a controller coupled to the HVAC system. The controller is configured to receive internal vehicle information, external static information, and external dynamic information, and to control operation of the HVAC system based on the internal vehicle information, external static information, and external dynamic information.

A vehicle climate system includes a blower and a controller. The controller is configured to, responsive to input of a particular user selected climate setting, operate the blower with an initial power having a predetermined value corresponding to the climate setting provided that cabin temperature is outside a predetermined range. The controller is also configured to operate the blower with an initial power having a value less than the predetermined value provided that the cabin temperature is within the predetermined range.

An air flow control system includes a forming portion, an outside air introduction door, and an air controller. The forming portion forms a front side communication port that communicates between the interior of the vehicle cabin and an engine compartment disposed on the front side in a vehicle traveling direction with respect to the interior of the vehicle cabin and accommodating a traveling engine. The outside air introduction door opens or closes an outside air introduction port to introduce an air flow from an outside of a vehicle cabin into the interior of the vehicle cabin. The air controller controls the outside air introduction door to open the outside air introduction port, and causes the air flow, introduced from the outside of the vehicle cabin into the interior of the vehicle cabin via the outside air introduction port with travel of the vehicle, to be blown from the interior of the vehicle cabin into the engine compartment through the front side communication port.

An autonomous vehicle includes a passenger cabin, a sensor group and a passenger cabin climate control system including a control module. The sensor group includes a passenger cabin odor sensor, an occupancy sensor and a vehicle speed sensor. The control module has a control logic adapted to purge an odor from the passenger cabin in response to data received from the sensor group indicating the presence of an odor in the passenger cabin, an unoccupied passenger cabin and the autonomous vehicle is moving at a minimum predetermined speed for a minimum predetermined time.

Systems and methods for controlling an environment of a vehicle receive information about a characteristic of at least one of the vehicle's operation, the vehicle's location, and an operator of the vehicle. The information is analyzed to assess a driving condition. An environmental setting of the vehicle is adjusted based upon the assessed driving condition.

A cabin pressure relief system for a motor vehicle includes a pressure relief valve and a control module. The control module is configured to open the pressure relief valve when an access door of the motor vehicle is opened and close the pressure relief valve in response to a specific event.

An evaluation device includes a set temperature evaluation portion, an ecological driving evaluation portion, and a notification portion. The set temperature evaluation portion determines a set temperature evaluation value based on a set temperature that is a target temperature. The ecological driving evaluation portion is configured to determine an ecological driving evaluation value based on at least the set temperature evaluation value. The notification portion is configured to notify the occupant of the ecological driving evaluation value. The level of power saving rises with change of the set temperature evaluation value or the ecological driving evaluation value. When the set temperature is changed, and the change of the set temperature causes increase of the level of power saving without decrease in power consumption of the vehicular air conditioner, the set temperature evaluation portion changes the set temperature evaluation value in the one of positive and negative directions.
